Student Activities
To create a Kodu world using tiles specific the BBC micro:bit, make sure you connect a micro:bit device and install the mbed serial port driver.
Welcome! This activity will teach you how BBC micro:bit shake interacts with Kodu. Let’s get started!
Step 1: World Design
Start Kodu Game Lab. Select the New World option from the Main Menu, and Kodu Game Lab will open and display a patch of ground directly in the center of the screen.
You want to enlarge the current land to have a quality gameplay experience. You might want to make this land 27 (gray).
- Walls After you design a large square, then you add a parameter that surrounds the terrain. The parameter should be a unique land type that will be the wall. You might want to make this wall land 57 (purple).
- Raise Wall You want to raise the wall that surrounds the ground. Select the magic brush to raise the land surrounding the terrain used for gameplay. The terrain for gameplay should appear below the remaining land.
- Center Line / Goal Outline You need to design the hockey center line and outline the goals. You want to make this land 45 (black). You want to create the hockey center line in the direction North and South by following the compass. You want to outline the goals in the direction East and West by following the compass.
- Goals Finally, you want to design the hockey goals. You might want to make this land 116 (orange) and land 61 (red). You want to outline the goals in the direction East and West by following the compass. The East goal is Land Type 116 (orange) and West goal is Land Type 61 (red).
Step 2: Add Objects
Select the Object tool (the Kodu icon on the toolbar). With a game controller, select the Object tool using the left thumbstick.
- For mouse users, move the mouse pointer to the center of the terrain and click and release the left mouse, which open the pie menu. Use your mouse to select two (2) Saucer objects or another moving object. Move the Saucer objects in front of their respective goals. Then change the Saucer to be the same color as their goals.
- For game controller users, move the camera to the center of the terrain and press the A button, which open the pie menu. Use the game controller to select the object. Use your game controller to select two (2) Saucer object or another moving object. After adding the objects to the terrain, press button B for the Tool Menu. Move the Saucer objects in front of their respective goals. Then change the Saucer to be the same color as their goals.
You want to add the Puck object. Move the Puck to the hockey center line, which is land 45 (black).
Finally, you want to create obstacles or additional defensive players. You want to add several Stick objects. Move the Stick objects to block Puck from entering the hockey goals, which is represented by land 61 (red) and land 116 (orange).
Optional: You want to create friends to watch the air hockey game. You can add additional objects and place these objects to watch from the wall.
Step 3: Program Saucer - Move Forward
You always want Puck to move forward quickly.
Step 4: Program Puck - Glow
